Running the same command shows that 139 is not binding to the broadcast
address:
tcp 0 0 192.168.1.100:139 0.0.0.0:* LISTEN 368/smbd
tcp 0 0 127.0.0.1:139 0.0.0.0:* LISTEN 368/smbd
udp 0 0 192.168.1.100:137 0.0.0.0:* 366/nmbd
udp 0 0 0.0.0.0:137 0.0.0.0:* 366/nmbd
udp 0 0 192.168.1.100:138 0.0.0.0:* 366/nmbd
udp 0 0 0.0.0.0:138 0.0.0.0:* 366/nmbd
OTOH, because I have a four IPs aliased to this machine, I have specific
interfaces listed in smb.conf:
interfaces = 192.168.1.100 127.0.0.1
bind interfaces only = yes
Hmm. Having read smb.conf man page again for bind interfaces only I guess it does make
this clear. Didn't read it properly last time I suspect.

Explains a few error messages I was getting then!

Um, yeah. I did... honest. ;-)
One other thing: I will need to share a locally connect printer off one of the
win2K boxes (I can't share it off the server as it'll be too far away physically).
I guess this shouldn't be a problem but can anyone think of any problems that might
arrise with this? Samba shouldn't have to be told about it, the printer should just
appear off the win2k box that it's attacted to right?
Thanks for your help.
